Blue Light Screen Protector for 23, 23.6, 23.8, 24 Inch Diagonal LED PC Monitor, Scratch-Resistant Computer Screen Blue Light Blocker, Blue Light Filter Hanging Type (W 21.3" x H 13.4")

I was having so much eye pain and irritation after work everyday, I put this on my monitors and problem solved. I do still get the feeling of my eyes being tired, but nothing like before that I literally had to use eye drops and close them cause I couldn't stand bright lights anymore.

As soon as hung it over the monitor I could feel my eyes relaxed. All day today my eyes did not feel tired.. It was a perfect size. I recommend this product.

I bought this item because the blue light from the overly bright screen was hurting my eyes, and I can tell the eye strain is down now. However, this screen is NOT matte, so it reflects everything in the room and all the light sources just glare right back at me from the screen. I also get tired of staring at my own reflection and everything in the room all day long.I'll probably be returning this item if I can find a decent alternative. If you don't mind the glare, the item is great. It covers my screen perfectly, and I take it on and off any time. My extra camera also fits nicely right on top of it, so very easy to install and take on and off.PROs:- easy to install;- looks good;- fits perfect to my 23.8, 9:16 monitor;- you can put an external camera on top of it.CONs:- too much reflection- doesn't darken the screen

I have these protectors on all monitors for years, when a new comp was installed I noticed my eyes were getting tired fast... decided to by these and was unpleasantly surprised! They prices are like 3 times what they were a few years ago, and not a lot of sellers selling them. They are just plastic, don't know why they have to be so expensive.As for effectiveness - you simply must have them if your eyes get tired fast.

left plastic to hold it up broker off as it was on my computer

It reflects so badly that you can’t see a lot of your screen unless you move your body to different positions. I would return but I’m a tired full time working mom and my kid throws things. At least it will protect my screen. I like seeing out the window behind me and knowing everything going on across the street, but it slows down work when I have to move to an area where the reflection doesn’t prevent me from seeing the screen

I had IOL surgery and my eyes just killed me working on my work computer. Headaches all the time!! After ordering this and using it, no more eye strain or headaches. Well worth the money. I even broke down and ordered one for my home computer monitor.

Could feel the difference in eye relief immediately.
